Water Level Stations

The Cooperative Observer Program (CO-OPS) and US Army Corps Poplar Island stations are primarily installed for delivering information on tides, water levels, and water temperature, but in many cases, they also provide meteorological data.

Poplar island is a single tide gauge station. CO-OPS is a consortium of more than 10,000 volunteers who take daily weather observations at National Parks, seashores, mountaintops, and farms as well as in urban and suburban areas. COOP data presented on the MARACOOS site is limited to coastal areas. COOP data are usually updated every few hours to once daily.
